Fast Photoreal Rendering +++ UPDATE +++

[Travis Cobbs]

There's no special command. IIRC, it simply replaces the stud.dat reference with a stud.ums reference for studs that have been detected as being mirrored. The stud.ums file has a matrix that mirrors the stud a second time, which results in a correct stud logo. Since the stud is symmetric with the exception of the logo, this second mirroring doesn't cause problems.
